The Milwaukee County Sheriff's Office (MCSO) maintains the county jail, provides bailiff services for the cirucit court, patrols the freeway, provides law enforcement presence at Milwaukee Mitchell International Airport and the Milwaukee County Institutions Complex. We maintain the peace throughout the County.

The Milwaukee County Sheriff's Office was founded in 1835. It is the oldest Sheriff's Office in the State of Wisconsin. The Sheriff's constitutional mandates include keeping and maintaining the peace throughout the county, maintaining the county jail, providing bailiff services for circuit courts and serving legal process. In the interest of flexible and efficient service to Milwaukee County citizens the Sheriff's Office is comprised of three bureaus: Administration, Police Services and Detention Services.

The Sheriff's Office, using community policing as an organizational philosophy, remains sensitive to the needs of the community. Recognizing that safety is a community responsibility, the Sheriff's Office engages the community. Knowing that our effectiveness is determined by public cooperation, the Sheriff's Office goal is to identify community leaders and work to facilitate the efforts of neighborhood leaders. The greater the degree of public involvement in addressing community problems the greater the potential for effective problem solving.

On Oct. 23, 2002, the Milwaukee County Sheriff's Office dedicated a new state-of-the-art-training academy located at 9225 S. 68th St. Franklin, Wisconsin. The academy is a 46,500-square-foot facility that includes eight classrooms, two lecture halls, a physical training room, mock training cells, three standard pistol ranges with a total of 20 firing points and an indoor 360-degree tactical firearms training room. Four of the classrooms can be joined and expanded to seat between 20 to 200 individuals. The two lecture halls each have seating for 57 people and can be joined so that up to 130 people can observe the same lecturer. The tactical firearms training room, or shoot house, allows realistic scenario based training.

Adjacent to the training academy is a memorial dedicated to the 13 Milwaukee County Sheriff's deputies who died in the line of duty while in service to the Milwaukee County community. The statute, titled "Call to Duty," sits atop a five-foot high octagonal marble base where each of the officer's names is inscribed. The site was selected because it can be viewed from the academy's main hall and will constantly remind deputies and students of the sacrifices all officers make to the community.
